JOHN T. H. PAUL, OF CHICAGO, ILLINOIS, ASSIGNOR TO E. GOLDMAN d: CO.,, INC, OF C'HIQAGO, ILLINOIS, A (ORPORATION OF ILLINOIS.

To all when it may concern:

Be it known that I, Jons T. H- PAUL, a citizen of the United States, residing at Chiin the county of Cook and State. of Illinors, have invei11 ted a new aRd useful 1m} rovement in asteurizm' g pparatus, o the follo w is a specification.

My invention re ates to im rovements in the clam of pasteurizers in w 'ch the material to be pasteurized, contained in pack- 1 1": liquids in bottlesis caused to travel slowly and intermittently through a series of compartments containing water at succewive temperatures increasing to that required for effecting pasteurization and thereafter decreasing, the packages intercepted in each compartment and carried about therein, by intermittent motion, or rotary carriers.

In the accompanying drawings, Figure 1 is a lanview of the ap aratus; 2 is a view 0 the same in side evation, and Fig. 3, an end view; 3 is a broken view in front elevation of the mutilated member :5 of the intermittent-motion device Fig. 4 is 'an enlarged section on line A, Fig. l, and 5, a similar section on line B, 2; Fig. 6 1s a section on line C, Fig. 5, and 7, a section on line D, Fig- 4; 8 is a per- 30 spective view of the tank in longitudinal section, showing its division into compartments which are, for the most part, Intereommunicating; Fig. 9 shows a steam-jet device in longitudinal section for heating and 35 circulating the water in the asteurizing compartments, and 10 an 11 are sectional views respectively of a thermostatdevice and an air-pressure valve-device for controlling the operation of the steam-jet I or o e o owing escnp tion, the m iiterial to be treated may be considered to be beer in bottles.

The tank 12 is shown of oblong rectangular 45 form and is divided into compartments, of

which six are shown (Fig. 8) by similar vertical double partitions l3, 14, 15 and 16, each forming between its sections an insulating air-space, and a le central partition 17 50 extending to a lesser eight in the tank than the others. A port 18 in the upper part of the partition 14 connects the compartments 22 and 23 and the latter communicates with the compartment 24 through a port 19 in the 55 lower part of the partition 13; the compart- Specifieation of Letters Patent.

ments 25 and 26 communicate through a ort 20 in the upper part of the partition 16, at the compartments 26 and 21 do not in;

tercommunicate directly and the com artments 21 and 22, which form the pasteunzing compartment, communicate over the upper edge of'the relatively lower partition 17 and through the bottom of the latter near its 0 posite ends. It would, of course, be possib e to construct the tank in sections joined to gether and forming the compartments.

A shaft 27' extends lengthwise and centrally through the tank, being journaled in the ends thereof and in the partitions. Rotary basket or receptacle carriers 28 are secured on the shaft to turn with it, one in each compartment, and are all of the preferred wheel-construction best illustrated of the one represented in Figs. 4 and 7: A pair of annular rims 29, 29 are connected by rock-shafts 30 journaled at uniform intervals apart in and extending between the rims which are rigidly connected by spokc's 31 with the central hub 32 secured on the shaft 27. The rock-shafts carry on corresponding ends cranks 33 which are fastened to an annular rim 34 connected by spokes 35 a ring 36 supported concentrically of the rim 34 by rotatably surrounding an annular hub 37, which is fastened eccentrically 85 upon the shaft 27 to rotate with it. The rim 34 thus rotates with the shaft and affords an eccentric connection therewith of the cranks for turning them as and for the purpose hereinafter described. On each 90 rock is secured to turn with it a basketr holder 38.

To drive the shaft 27 it carries on one end a gear-wheel 39 to he engaged by an intermittent drive of the preferred construction illustrated, comprising a rotary shaft 40 journaled in suitable bearings and carryin on one end a mutilated car 41 consisting o worm-sections 42 extending part way about the shaft and straight teeth 43 extending about the remaining portion of the shafts circumference and joining the ends of successive worm-sections. On the opposite end of the shaft 40 is a worm-wheel 44 meshing with a worm 45 on the drive-shaft 46, which is j ournaled in suitable hearings and carries on one end a belt-pulley 47 and on its op 0- site end a beveled pinion 48 meshing wi a similar pinion 49 on a shaft 50 journaled in on the base of the partition 17. 110

The shaft 50 carries on each end a shielded agitator51 in an opening in the base of the partition to act upon the water in both compartments 21 and 22, as and for the purpose hereinafter explained.

A gear-wheel 52 on the end of the shaft 27 carrying the gear 39 meshes with an idler 53, which in turn meshes with a pinion 54 on a shaft 55 journaled, like the idler 53 and shaft 27, in bearings in a frame 56 at the adjacent receiving end of the tank and carrying a pair of sprockets 57 connected by inclined chains 58 with similar sprockets 59 on a shaft 60 journaled in bearings on a lower frame 61. At the opposite, delivery end of the tank is provided a frame 156 like the frame 56 and having journaled in it a shaft 155 carrying sprockets 157 connected by inclined chains 158 with similar s rockets 159 on a shaft 160 journaled in a ower frame 161, all as at the receiving end of the tank, except that the chains 158, forming a conveyer, must travel in'the direction opposite that in which the conveyer-chains 58 travel, and to that end are suitably geared to the shaft 27, as indicated in Fig. ,1, by the interposition in the gear-train of an additional idler. On each pair of the chains 58 and 158 are fastened at uniform intervals apart platforms 62, each consisting, as its preferred construction, of a rectangular frame (Fig. 1) in which rollers 63 are journaled, with one end of the frame pivotally connected with the pair of chains and the other end connected therewith by links 64, whereby the roller platforms are rendered flexible to adapt them to pass freely about the sprockets and always occupy a horizontal position in their travel along the inclined way of the conveyer to properly support baskets 65 filled with bottles containing the beer to be received into and delivered from the tank.

The platform-rollers facilitate imposing the boxes on and removing them from the platforms.

As will be hereinafter more fully explained, the operation of the machine involves intermittent rotation of the shaft 27 to bring a longitudinal series of the holders 38 on successive carriers 28 in horizontal alinement with the feed and dischar e ositions of the baskets 65, so that eac a ternate time that the carriers are arrested a fresh box may be introduced into place upon the first carrier, and the bzrkets ahead of it advanced u onsuccessive carriers, while the alining bas et on the final carrier is advanced out of the tank upon the deliverycarrier. To effect the automatic advancement of the baskets upon successive holders 38 a rod 66 is. supported to adapt it to be reciprocated longitudinally in bearings provlded on the horizontal ends of arms 67 of inverted fl. shape rising at intervals from the tank-ends and partitions between them to extend the rod-bearings along the longitudinal center of the tank, and pusher-fingers 68 de end at proper-intervals rigidly from the rod to engage the rear ends of the baskets. For reciprocating this rod it has a link-connection 69 with a horizontal crank-arm 70 on the upper end of a vertical rock-shaft 71 (Fig. 3) ournaled in bearings res ectively in the flange on the up er edge of t e tank and in a frame 72, and t 's vertical shaft carries on its lower end'a segmental pinion 73 meshin with a rack 74 supported for longitudina y reci rocable movement in the frame 72. In t 'sframe is also journaled a shaft 75 provided witha toothed wheel 175 which meshes with a pinion 140 on a shaft 40, the shaft 75 carrying a cam 76 of the construction shown, adapting it b engagement with it-of a stud 77 depending om the rack to reciprocate the latter by a partial rotation of the shaft 40.

An important feature of the present invention is that of the circulation of the water. in the tank, to maintain'that in each endcompartment 24 and 25 at practically the same temperature (about 25 R. for beer), that in each intermediate compartment 23 and 26 at practically the same temperature of 40 R. (for beer) and that in each central compartment 21 and 22 at the pasteurizing temperature, which is about 48 R. for beer; and the course of circulation is that, as in dicated by arrows (Figs. 2 and 8), from the compartments 21 and 22 through the upper port 18 into the attemperatmg-compartment 23, thence through the lower port 19 into the receiving-compartment 24, thence throu h a ipe 78 (only indicated in Fi 8) into t e delivery-compartment 25, and om the latter through the upper port 20 into the attemperating-compartment 26. For producing the circulation and heating the water for the pasteurizing action the jet-pum device 79 is rovided which is most cliiarly i]lustrated 1n Fig. 9, with a steam-sup ly pipe 80 leading into its casingand its v vestem 81 connected for automatic control of the device with a spring retracted diaphragm 82 actuated by air-pressure directed against it through .aipe 83. The flow of air under pressure to t e diaphragm is automatically controlled by the valve-device 84 most clearly illustrated in Fig. 11 and involvin the adjustable spring su ported ball-vzfive 85 interposed, in a vented casing 86, between the air-pressure su plyipe 87' and the pipe 83, the control of t e v ve be.-

ing efiected by a lever 88 engaging at 6ne.

ders it o n to the atmosphere to expose thereto t e diaphragm 189.

The mechanism shown in Figs. 9 to 11, inelusive, and which is used by preference in connection with the present invention, is fully shown and described in my United States Letters Patent No. 886,012, dated April 28, 1908, and need not, therefore, be more elaborately described herein. This mechanism is (in licatcd on opposite sides of the tank, with a flow-pipe 93 leading into the casing of the steam-jet pump from a pipe 94 which connects the two compartments 21 and 26 near their upper ends outside the tank, and a dischar e-pipe 95 leading from the pump into the lower part of the compartment 22. The tank is provided with an overflow-pipe 96 (Fig. 1) leading preferably to a sewer (not shown), and draw-off cocks 97 are shown on the lower parts of the compartments.

To start with, the tank is filled with cold water, which may be introduced in any desired manner, as through its open top by means of a hose. The jet-pump, by its operation, draws water through it from the uper parts of the compartments 26 and 21, heats it and discharges it in the heated condition into the bottom part of the com art? ment 22, and the water so heated circu ates in the two compartments 21 and 22 over and under the partition 17, under the action of the agitators 51, to,eventually raise the water therein and maintain it at the pasteuri? ing temperature. From the. compartment 22 the circulation proceeds in the manner heminbefore described to heat and maintain the water in each compartment 23 and 26 at the required temperature for preparing; the

bottles to enter the pasteurizing centralcompartments (which form practically a single compartment), and to heat and maintain the water in'the end-compartments at the required temperature to adapt them, respectively, to receive the cold bottles without danger of fracturing them and deliver the same to the atmosphere with like lack of dan ger.

'ith the circulation thus proceeding, the

operation of the machine is as follows: Rotation of the shaft 46, which maintains thev agitators 51 in constant motion, slowly drives the shaft 40 continuously to cause the mutilated-gear device 41 to turn the carrier-shaft 27 through part of a rotation by the action of the worm-sections 42 and then, by engagement of the tootlvsections 43 with the gear 39, arrest the rotation of the carrier-shaft until the worm-sections again engage said gear. The arrangement is such as to cause each engagement of the worm-sections 42 with the gear to turn each of the carriers 28 one half the distance between successive holders 38, so that with each carrier provided with ten holders, as shown, it requires two actions of said worm-sections to bung a longitudinal series of the holders into registration with the receiving and delivery points on the tank-ends, one of such actions serving to remove the holders out of that registration and out of the return-path of the pusher-fingel-s for the 'purpose hereinafter explained. This rotating shaft 27 furthermore drives the conveyors at correspondingsneed, that at the receiving-end of the tank sing sup- )licd with baskets containing the beerliottles by an attendant who places such a basket on each lowermost patform 62 as it arrives in position to receive the sam he movements of the parts are so timed that with a basket conveyed to the receivingpoint on the tank the carriers 28 will be orrested to aline a longitudinal series of holders 38 with that oint, and the shaft 40, in rotating, tums t e cam 76 to move the rack 74 in the direction to so turn the shaft-71 as to cause it to move the rod 66 in the direction toward the delivery-end of the tank, thereby engaging with the. aforesaid basket pusherfinger 68 then behind it, to advance that basket upon the holder 38 in position to receive it on the first rotary carrier 28. The next partial turn of the series of carriers takes the basket out of the return-path of the fingers 6S, permitting the cam to return them to normal position, wherein the first finger will be behind the next basket brought by the conveyor into the rcccivinp: position. The next. partial turn of the carriers brings the next succeeding holder on the first carrier into )osition to receive the basket thcnin place to be advanced by the first pusher-lingcr. filled with the baskets, and each is intermittently rotated in each compartment to suhjectthe bottles for the proper )rolonged period to the temperature in mat compartment, and at the end of each period of such subjection baskets in proper position are transferred to the successive compartments to be preliminarily heated in the compartmcnt 23 after being warmed in the compartment 24 and thus prepared to enter the compartments 22 and 2! to be pastmiri'lzcd thcrcin, whence they enter the compartment .26 for preliminary reduction therein of their temperature and then attain the compartment 25 for successive delivery from the top thereof at about atmosphere temp rature to the convcycr at that end of the tank. from the discharge end of which an attclidanl removes thcm in succession.

As will be observed, by the crunlecormcction 33 between the eccentric rim 34 and each rock-shaft 30 of the respective carrier 28, correspondingly with which th rim rotates, the holders on each carrier are maintained at all times in required horizonlal posit-ion to support in that position he baskets 65.
